more weighty texts that you should consider include the original classic poems Iliad and Odyssey by Homer

others to consider are the works of Tom Holland - Persian Fire, Rubicon, Dynasty and others
anything by respected scholar Mary Beard, including her book about Roman History, SPQR

Competitions; The University of Cambridge Faculty of Classics run around 6 essay competitions with Classical themes. Oxford run a competition for state school students only. Specific Colleges in Oxford offer additional competitions such as; The Mary Renault Prize (Classics); St John's College offer several prizes (return to the site to find details as they emerge). UCL ran a Greek and Latin essay competition (check back for details for this year).
Events and Activities; Attending Classic plays is a fantastic way to learn, and then comparing the play you have seen to the original as written can generate some interesting observations, check your local theatres for listings. Things that you might consider doing are to start a Classics Club in your school looking at plays or discussing myths, you might start a Classics Drama Club or you might record some short lectures for younger pupils.
